No no, nothing's wrong!! you'll be amazed that they are designed that way. on a RHD Td5, it list to the left on the LHD it list to the right.
I've ripped out my old set of springs (3.5yrs) and got them changed to the scorpion one and they are a good 1 inch different both on the old and new.
the td5 90 supposed to be slightly tilted forward too.
Now you wonder why?
I've tired to level the car out before on the old set and when i've that done, it collects water. especially in the gutter below the windscreen.
There must be more reasons like...
1. back in the Tdi days, the tank was under the driver seat, so the spring on the DS was to compensate for that weight?
2. LR drivers are tuff and adventure comes alone? so no need passenger.
Happy landie-ing...
